Clinical outcomes of laparoscopic cholecystectomy in elderly patients after preoperative assessment and optimization of comorbidities.

Backgrounds/aims: Early laparoscopic cholecystectomy is considered as the standard treatment of acute cholecystitis. However, whether this procedure is desirable in elderly patients with acute cholecystitis is not clearly elucidated. In this study, we aimed to evaluate the effects of thorough preoperative assessment and consultation for complications on clinical outcomes in elderly patients over 65 and over 80 years.

Methods: We retrospectively analyzed 205 patients who were diagnosed with acute cholecystitis between January 2010 and April 2018. The patients were assigned to three groups: group A (aged <65 years), group B, (aged between 65 and 79 years), and group C (aged >79 years). Laparoscopic cholecystectomy was performed after preoperative evaluation, such as echocardiography, pulmonary function test, and consultation about past history.

Results: Significant differences were not found in the complication rate among the age groups. Open conversion was required in eight of the 114 patients in group A, seven of the 70 patients in group B, and one of the 21 patients in group C. However, no statistical significance was found. Moreover, no difference was noted in the start of the meal and the period from surgery to last visit, but hospital stay after surgery was longer in groups b and c.

Conclusions: When sufficient preoperative assessment and treatment were performed, complication and conversion rates were not significantly different among the age groups. In extremely elderly patients, preoperative evaluation and elective laparoscopic cholecystectomy were desirable.
